Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disc clipping device, and more particularly, to a disc clipping device that enables automatic loading of discs using a small and thin clipper.

A disc loading device is known that loads a video disc or audio disc into the player body without removing it from the jacket, but with conventional disc loading devices, the disc must be inserted into the player body along with the jacket. In addition, there are other loading mechanisms used for needle-type video discs that use a case called a gear day, and load the disc by setting the disc in the sleeve of the case. The Kiaday mechanism is relatively expensive, and if this mechanism were to be popularized for normal audio disks (33.3 rpm), it would be extremely difficult to realize it because it would require a certain degree of standardization. There were flaws. In addition, the mechanism for placing the disk on the turntable is complicated and has the disadvantage of being prone to failure.

The present invention eliminates the above-mentioned drawbacks of the conventional method, and has a clipper consisting of a pair of clamping members waiting in a jacket guide protruding from the periphery of the disk loading opening of the player body, and the jacket is placed against the jacket guide. By switching the energization to the solenoid to displace the wedge together with the plunger and mechanically displacing the clipper, it is possible to clip only the disk. It is an object of the present invention to provide a disk clip device that can be configured to be small and thin.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. Figures 1 and 2 are a schematic perspective view and an enlarged perspective view of essential parts of an example of a disc player to which the disc clipping device of the present invention is applied, and Figures 3A,
B and FIGS. 4A and 4B show a plan view and a side view of an embodiment of the disk clipping device in the non-clipping state and in the clipping state, respectively.

In FIG. 1, disk player 1 is disk player 2.
The object is a device that can be loaded into the player body 1a while remaining inside the jacket 3 without taking it out from inside the jacket 3. Player body 1
A disk loading port 4 is formed in the front of a.
A jacket guide 5 is provided protruding from the periphery of the disk loading opening 4. Jacket guide 5 includes
The opening of the jacket 3 in which the disk 2 is housed is applied in an open state, and the jacket 3 is thereby positioned. Reference numeral 6 denotes threads for supporting the disk 2 when the disk 2 is drawn into the player main body 1a, and is provided on both sides of the turntable 7 so as to be movable up and down.

Reference numeral 8 denotes a disk clipper, which in this embodiment is fixed to a loading belt 9 stretched above the turntable 7. By driving the loading belt 9, it can clip a disk just above the turntable 7. Displace from end to end. Reference numeral 10 is a motor capable of forward and reverse rotation for driving the loading belt 9, and reference numeral 11 is a stopper that restricts the entry limit position of the disk 2.

As shown in FIGS. 2 and below, the disk clipper 8 has a pair of plate-shaped clamping members 12 with pads connected by hinges in a beak-like manner so as to be freely openable and closable, and these clamping members 12 are connected to a lever part in this relationship with respect to the hinge joint location. A tension spring 13 tensioned between 12a biases them in the direction of separating them from each other. Both clamping members 12 are normally on standby in the jacket guide 5 in an open state. On the other hand, a conical wedge 14 is inserted between both lever portions 12a so as to be freely advanced and retractable, and the wedge 14 is integrally formed with a loop-shaped plunger 15a. 15b is
The solenoid constitutes the plunger solenoid mechanism 15 together with the plunger 15a, and attracts the plunger 15a against the return spring 16 by the magnetic force when energized and excited. At this time, the wedge 14 is displaced in a direction in which the large diameter portion enters between the lever portions 12a, thereby opening the lever portions 12a and closing the clamping members 12 together.

The solenoid 15b is energized by a closing signal from a disk detection leaf switch 17 provided near the disk loading port 4 shown in FIG. This leaf switch 17
is closed by the disk 2 when the jacket 3 is applied to the jacket guide 5.

When loading the disk 2, first the jacket 3 is pressed from both sides to inflate the center part and open the mouth of the jacket 3. At this time, the disk 2 inside the jacket 3 is pushed by the left and right edges of the jacket 3 and is held within the jacket 3 without play.

Next, insert the opening of the jacket 3 into the jacket guide 5.
Apply to. At this time, the leaf switch 17 is actuated by the disk 2, and the solenoid 15b is energized. As a result, the plunger 15a is attracted by the solenoid 15b against the spring 16 from the state shown in FIGS. 3A and 3B, and the large diameter portion of the wedge 14 enters between the lever portions 12a.

Here, when the jacket 3 is applied to the jacket guide 5, the end of the disk 2 inside the jacket 3 enters between the clamping members 12 which are retracted within the jacket guide 5, so that the disk 2 is not attached to the lever portion 12a. With the displacement of , as shown in FIGS. 4A and 4B, it is clamped from above and below by the clamping members 12. As a result, the disk 2 in the jacket 3 is moved to the clipper 8.
It is firmly clipped by.

When clipping is performed by the clipper 8, the loading belt 9 is driven to run, and the disc 2, while being clipped by the clipper 8, slides on the sled 6 and is drawn into the player main body 1a. When the disk 2 is pulled in until it comes into contact with the stopper 11, the clip by the clipper 8 is released and the sled 6 is lowered below the turntable 7, so that the disk 2 is placed on the turntable 7.

Note that when taking out the disc 2 that has finished playing from inside the player body 1a, remove the empty jacket 3 from the player body 1a.
By applying the disk to the jacket guide 5 and closing the disk recovery switch (not shown), the operation opposite to that during loading is performed. In this case, the clipper 8 pushes the disc 2 out of the player main body 1a while still clipping it, so that the disc 2 is recovered into the jacket 3.

Here, the disk clipping device 18 is composed of a jacket guide 5, a clipper 8, a wedge 14, a plunger/solenoid mechanism 15, and the like. By adopting this arrangement, the disk clip device 18 can be integrated into the player main body 1a in an extremely compact manner because the disk clip device 18 can be connected in a positional relationship that does not take up the width or thickness.

Also, the clipping operation of the clipper 8 and the clipping operation of the clipper 8
Since the pulling-in operation of the disk 2 is carried out reliably by a simple mechanism, failures are extremely rare compared to a structure in which the disk is inserted into the player body together with the jacket.

In the above embodiment, instead of the leaf switch 17 for disk detection, for example, an optical switch combining a light emitting element and a light receiving element may be used.

As explained above, according to the disc clipping device for a disc player according to the present invention, when the jacket is applied to the jacket guide, the end of the disc inside the jacket enters the clipper waiting inside the jacket guide. , the wedge connected to the plunger is displaced at the same time as the energization of the solenoid of the plunger solenoid mechanism is switched, and the pair of clamping members forming the clipper are mechanically closed together with the displacement of the wedge to clip the disc. The disc can be easily and securely clipped by simply placing the jacket on the jacket guide without removing the disc from inside the jacket, and the clipper is configured to pull only the disc into the player body while leaving the jacket outside the player body. Therefore, the automatic disk loading mechanism can be made simple, and since the clipper is mechanically opened and closed by an electromagnetically driven wedge, the clipper and plunger solenoid mechanism can be made small and thin. As a result, the player body itself can be made smaller.
